Little Johnny attended a horse auction with his father. He watched as the father moved from horse to horse, running his hands up and down the horses' legs, rump and chest.

After a few minutes, Little Johnny asked, "Pop, why are you doing that?"

His father replied, "Because I'm thinking of buying these horses."

Little Johnny looked worried and said, "Then I think we'd better hurry home right away!"

"Why?" his father asked.

"Because the UPS man stopped by yesterday, and I think he wants to buy Mom!"
